An electrodeposition coating composition is described comprising:n (a) an aqueous dispersion of a water-dispersible, electrically-depositable, at least partially neutralized cationic resin, and (b) polymer microparticles, said polymer particles being prepared by:n (1) blending an acid-neutralized tertiary amino-functional acrylic polymer and a polyepoxide, (2) dispersing the blended mixture in an aqueous medium to form a dispersion of microparticles of the blended mixture, and (3) heating the dispersion to crosslink the acrylic and polyepoxide in the microparticles. |
